Starting Monday, the Eastern Church Christians enter the Holy Week (also called the Passion Week), the most important period of the Church calendar, when the events experienced by Jesus one week before his resurrection are celebrated. Each day of the Holy Week is a new step of Jesus Christ towards Crucifixion and Resurrection.
The most important events in the history of salvation take place in the week before the Resurrection of Jesus, starting with the teachings send by Jesus to his apostles and ending with the sacrifice on the Cross.
Monday, Tuesday and Wednesday are the days when each Christian prepares to understand the meaning of Jesus’ birth, passions and death, and namely defeating the sins and death through his sacrifice.
On Monday we recall Blessed Joseph of the Old Testament who was beaten by his brethren, left for dead, and enslaved by foreigners.
Tuesday is dedicated to the Sermon by means of which Jesus Christ foresaw the destruction of the temple in Jerusalem, as well as his own Resurrection.
On Wednesday the Church gives us the example of the adulteress who, once she met the Lord, realised the gravity of her sins, fell down before Him and washed His feet with her tears and precious perfumes, as well as the example of Judas who betrayed Jesus for a bribe of "thirty pieces of silver" by identifying him with a kiss—the "kiss of Judas"— to arresting soldiers of the High Priest Caiphas, who then turned Jesus over to Pontius Pilate's soldiers. Wednesday is declared fasting day by the Church.
